Intercropping grain legumes with cereals is an efficient management method to reduce weed problems in grain legume production in organic farming

Independent of crop yield performance between sites and the varying conditions of weeds in terms of species and biomass, intercrops and barley sole crops reduced weed pressure better than pea sole crops in all cases, with no difference intercrop designs. A better efficiency of barley and the intercrops for DM accumulation and soil N uptake was the explanation for the greater competitive ability against weeds of these crops compared with pea sole crops. Intercropping pea with barley appears to be a very efficient management method for reducing weed infestation in organic farming, whereby mechanical weeding and burning of weeds can be avoided.
